Page 14: Suggested Installation And Operation
S E C T I O N 5 Suggested Installation and Operation E Series gear pumps are designed to meet the performance requirements of even the most demanding pumping applications. They have been designed and manufactured to the highest standards and are available in a number of different sizes to meet your pumping needs. - Page 15 BASE INSTALLATION AND GROUTING NOTE: Before the baseplate is installed, it is advisable to thoroughly clean the underside to enable the grouting to adhere to it. Do not use oil-based cleaners since grout will not bond to it. Once the concrete pad has cured, the baseplate can be carefully lowered over the anchor bolts. Place shims or tapered wedges under the baseplate at each of the anchor bolt positions to provide about 19 mm - 38 mm (0.75"...
- Page 16 ALIGNMENT OF PUMP/DRIVER SHAFTS WARNING! NOTE: Driver power must be locked out before beginning any alignment procedure. Failure to lock out driver power may result in serious physical injury. NOTE: Proper alignment is the responsibility of the installer and user of the equipment. NOTE: Check alignment if process temperature changes, piping changes and/or pump service is performed.
- Page 17 Alignment must be done at several different times: Prior to grouting baseplate during installation After grouting baseplate and tightening anchor bolts After attaching suction and discharge piping prior to initial operation Hot alignment after equipment temperatures have stabilized After pump maintenance bearing housing is removed Since the E Series pump is foot-mounted, its shaft centerline will rise when handling pumpage at elevated temperatures.
- Page 18 LASER ALIGNMENT METHOD The laser alignment method is preferred for checking alignment. Laser alignment is usually the most accurate method. Follow the laser alignment equipment manufacturer’s instructions for this method. As previously mentioned, pump and motor shafts need to be in alignment while they are at their intended operating temperature. When the shafts are aligned “cold”...

Page 20: Pump Adjustment And Maintenance
S E C T I O N 6 Pump Adjustments and Maintenance CHANGING PORT ORIENTATION ONLY (Shaft Rotation Unchanged) The following instructions apply for changes when the direction of shaft rotation will not change, such as changing from RT to TL. Since the shaft rotation is unchanged, the discharge and suction positions relative to the casing and head will not change and, therefore, the cooling circuit plugs will not be moved. - Page 21 If the pump is equipped with a relief valve, disassemble the relief valve per the instructions in Section 7, Pump Disassembly & Repair Processes. Disassemble pumping chamber per the instructions in Section 7, Pump Disassembly & Repair Processes. Remove the casing orifice plug (not found on all configurations) and casing block-off plug. Install the casing orifice plug (if required) behind the DISCHARGE port.
- Page 22 CHANGING RELIEF VALVE PRESSURE SETTING (E1-2 thru E1-82 Models) In order to maintain the integrity of the relief valve setting, the E1-2 thru E1-82 E Series relief valves are not externally adjustable. Instead, the setting is adjusted by changing the poppet and spring. Obtain a new poppet and spring for the desired relief-valve setting.
